    Re: OpenGL 3 Updates

    t_{to release} \in (0, \infty) is pretty well defined, doesn't help us much tho :P [/QUOTE]

    Sure, let's start with that and then we can play the binary search game until it's more reasonable. Go...

    There is a pretty well defined release window for 3.1, but no details I can share yet.

    Re: OpenGL 3 Updates

    Hi Simon -

    The general idea for 3.1 and beyond includes a few components:

    - doing a more consistent and timely job of exposing hardware functionality
    - reducing and removing deprecated...

    I'm sorry you feel that way Korval - not all project management decisions are easy ones. The one made to table LP was extremely difficult.

    Re: OpenGL 3 Updates

    So a 3.0 "full" context has everything described in the spec. Call that X.

    A 3.0 "forward compatible" context has everything in 3.0 minus Appendix E features. Call that Y; and Y<X.

    I think feedback on the direct state access extension would be very valuable to the working group. Not talking about it "until it's core" creates a chicken and egg situation. If a lot of developers...

    Re: OpenGL 3 Updates

    One feature of GL 3.0 is a mechanism for requesting a context where the deprecations are enforced - this was put in to give developers a way to run their apps in this mode early on.
